I am new to kegging and have had an attempt at bulk priming. My first attempt worked really well however my second attempt not so much. My method is to add my dex to the keg then fill the keg the same as i do when I force carb. Burp it then leave for 2 weeks to carbonate. This time after a little over 2 weeks I put the keg in the fridge to chill and 24hours later poured a beer however it was flat and sweet. It has been in the fridge for about a week now. Can i just remove it and let it warm up to ferment the dex or is it stuffed?
